RMgX + CO 2 → ether dry Y ⟶ H 3 O + RCOOH What is Y in the above reaction?

Options

  1. AR 3 CO - Mg + X
  2. BRCOO - X +
  3. CRCOO 2 Mg
  4. DRCOO - Mg + X

Correct answer

D. RCOO - Mg + X

Step-by-step solution

Grignard reagent on reaction with carbondioxide in presence of dry ether forms an addition product which on hydrolysis produces carboxylic acid. Hence, Y in the above reaction is RCOO - Mg + X
